Note:
1. Cut-off voltage of inverter should be 10.5V (Minimum).
2. There should be a periodic Bench-Charging of the battery after every three months from the date of installation.
3. S = Series connection; P = Parallel connection; e.g. 2S x 2P = A string containing 2 nos. batteries in series and 2 nos. such strings in parallel
Consideration of Electrical Load Details
     • 1 no. Fan = 80 Watt
     • 1 no. Tube light = 40 Watt
